[0027] Furthermore, the limit frame 3 is threadedly connected to the screw rod 10, the positioning piece 11 is rotatably connected to the screw rod 10, and the rotating wheel 12 is fixedly connected to the screw rod 10, so that the user can rotate the screw rod 10 through the rotating wheel 12, thereby causing the screw rod 10 to move left, driving the positioning piece 11 to press against the motor 4, and maintaining the stability of the motor 4 on the limit frame 3. The output shaft of the motor 4 is fixedly connected to the eccentric wheel 5, so that the motor 4 can drive the eccentric wheel 5 to rotate after starting.

[0028] Furthermore, when the limiting plate 6 slides on the eccentric wheel 5 through the slide bar 601 and the slide groove 501, it drives the fixed seat 7 and the imitation kneading block 8 to move synchronously, thereby adjusting the eccentricity of the imitation kneading block 8 when it rotates, and when the positioning screw 9 is screwed on the eccentric wheel 5 through the positioning screw hole 502, the screw head of the positioning screw 9 can press the limiting plate 6 against the eccentric wheel 5, thereby maintaining the stability of the limiting plate 6 on the eccentric wheel 5, so that the limiting plate 6 can be driven to rotate when the eccentric wheel 5 rotates.

[0029] Furthermore, the limiting plate 6 is fixedly connected to the fixing seat 7, and the fixing seat 7 is fixedly connected to the imitation kneading block 8, so that when the limiting plate 6 rotates, it can drive the fixing seat 7 and the imitation kneading block 8 to rotate synchronously.

[0034] Follow the steps below during use:

[0035] Step 1: Pass the motor 4 through the limit frame 3, and rotate the screw rod 10 through the rotating wheel 12, so that the screw rod 10 and the positioning piece 11 move to the left, so that the positioning piece 11 and the limit frame 3 are against the motor 4, so as to maintain the stability of the motor 4;

[0036] Step 2: Adjust the positions of the limit plate 6, the fixed seat 7 and the imitation kneading block 8 on the eccentric wheel 5 through the slide bar 601 and the slide groove 501 as needed, adjust the eccentricity of the imitation kneading block 8, screw the positioning screw 9 into the positioning screw hole 502, so that the screw head of the positioning screw 9 presses the limit plate 6 against the eccentric wheel 5, and maintains the stability of the limit plate 6, the fixed seat 7 and the imitation kneading block 8.

[0037] Step 3, the controller 14 is used to set the number of rotations, speed and timing start and stop of the output shaft of the motor 4, so that the imitation kneading block 8 rotates to imitate the kneading action of the hand;

[0038] Step 4, fix the contact lens on the lens receiving bracket 17, start the electric push rod 15 through the controller 14, so that the electric push rod 15 drives the pressure sensor 16, the lens receiving bracket 17 and the contact lens to move upward, so that the contact lens contacts the imitation kneading block 8, and the imitation kneading block 8 rubs the contact lens.
